Question

Explanation:

Alcohol is a central nervous system depressant. It impairs cognitive functions like concentration and comprehension, and reduces motor coordination. While in some cases alcohol may cause temporary minor heart rate changes, it is not a direct, primary effect; the other options are well-documented immediate effects of alcohol consumption on the brain and motor skills.

Increased heart rate
